How much money do I need to start Amazon FBA in the UK?

A realistic UK Amazon FBA startup budget is £500-2,000 for product capital plus around £100/month for tools and the Amazon Professional Seller account. Beginners can start with as little as £200-300 if they focus purely on Retail Arbitrage with quick flips, but £500 in Online Arbitrage capital is the threshold where the workflow stops feeling restrictive.

The actual line items

(1) Amazon UK Professional Seller account — £25/month + VAT (£30/month total). The Individual plan is free but charges 75p per sale and bars you from many categories. Don't bother with Individual past your first 10 sales. (2) Initial product capital — £500-2,000 depending on your model. RA and OA can run on £500 with quick turn. Wholesale typically requires £2,000+ for a meaningful first order. (3) Tools — Keepa subscription (£15/month for paid version, essential for buy-box history), SellerAmp SAS (£20/month) for fast scanning. (4) Prep — either £0.50-1.00 per unit at a UK prep centre, or you do it yourself.

Costs new sellers always forget

Inbound shipping to FBA — the 200g box of toothpaste you bought for £2 costs another 50p+ to get into Amazon. Returns — Amazon UK return rates are typically 2-5% by category; budget that into margin calculations. UK VAT — once your turnover passes £90,000 you must register for VAT, which means remitting 20% on output AND being eligible to reclaim input VAT. Plan for this BEFORE you cross the threshold; many UK FBA sellers get blindsided. Storage — Amazon charges UK FBA storage fees that double in Q4. Slow-moving inventory burns cash.

Realistic 12-month progression

Month 1-3: £500-1,000 capital, OA / RA only, 5-15 sales/month, learning. Month 4-6: scale OA, start adding A2A flips, 20-50 sales/month. Month 7-12: open first 1-3 wholesale accounts (this is where serious money lives), 100+ sales/month. The Inner Circle FBA's wholesale masterclass (6-week live cohort, £199-499) is built specifically around the wholesale opening at month 6+ — but only if you've done at least 3 months of OA/RA first.

Free vs paid tools — what's actually worth it

Free tools that work: Amazon's own Seller Central app (basic but ok), Google Sheets for tracking, our public FBA fee calculator at theinnercirclefba.com/fba-fee-calculator (live SP-API data, free, no signup). Paid tools that pay for themselves: Keepa (essential), SellerAmp (saves hours), an Inner Circle membership at £29.99/month (one good lead a month covers the cost). Tools that aren't worth it for beginners: Helium 10, Jungle Scout (built for Amazon US private-label, overkill for UK arbitrage).
